可編程控制器、HMI人機界面的電磁干擾的主要來源和途徑
1、來自空間的輻射對可編程控制器、HMI人機界面的干擾。
空間輻射電磁場主要來自現場動力線路、電氣設備的暫態過程、雷電、無線信號、高頻感應加熱設備等，與現場設備布置及設備所產生的電磁場有關?？删幊炭刂破?、HMI受到的輻射干擾，主要通過兩條路徑：一是對通信網絡的輻射，由通信線路感應引入干擾；二是直接對可編程控制器、HMI內部的輻射，由電路感應產生干擾。
2、來自電源的傳導對PLC控制器的干擾
PLC控制器電源通常采用隔離電源，但因其機構及制造工藝等因素使其隔離性并不理想。實踐中，因電源引入的干擾造成PLC控制器故障的情況很多。
PLC控制器的正常供電電源均由電網供電，由于電網覆蓋范圍廣，它將受到所有空間電磁干擾而在線路上感應電壓和電流，尤其是電網內部的變化、大型設備起停、開關操作浪涌、短路電流沖擊、交直流傳動裝置引起的諧波等，都通過輸電線路傳到電源原邊，產生干擾。主要通過兩條路徑：一是通過PLC控制器供電電源引入的干擾；二是通過變送器電源或共用信號儀表的供電電源引入的干擾。
3、來自信號線引入的傳導對可編程控制器的干擾
與可編程控制器連接的各類信號傳輸線，除了傳輸有效的各類信號之外，還會受到外部干擾信號侵入。由信號引入的干擾會引起I/O信號工作異常和測量精度大大降低，嚴重時將引起元器件損傷。干擾主要有兩種途徑：一是通過變送器供電電源或共用信號儀表的供電電源串入的電網干擾；二是信號線受空間電磁輻射感應的干擾，即信號線上的外部感應干擾。對于隔離、屏蔽性能差的系統，還將導致信號間互相干擾，引起共地系統總線回流，嚴重時造成系統誤動和死機。
